A balloon filled with helium gas at 20°C occupies 2.91 L at 1.00 atm.The balloon is immersed in liquid nitrogen at -180°C,raising the pressure to 5.20 atm.What is the volume of the balloon in the liquid nitrogen?
A)0.178 L
B)5.62 L
C)5.04 L
D)0.199 L

The volume of the balloon in liquid nitrogen can be calculated using the combined gas law, which is $P_1V_1/T_1 = P_2V_2/T_2$. Given $P_1 = 1.00$ atm, $V_1 = 2.91$ L, $T_1 = 20°C = 293K$, $P_2 = 5.20$ atm, and $T_2 = -180°C = 93K$, solving for $V_2$ gives approximately $0.178$ L.
